Abstract
The proper design procedure is a critical factor that restricts the capacity of
an unmanned aerial vehicle (UAV) to fly freely for long periods. A UAV could fly
with a high lift force and less drag if the aerodynamic performance of the wings
is taken into account. With the aim to identify the best configuration that
provides a high aerodynamic ratio (L/D) at low
flying speeds, the current study investigates single-taper wings with three
different configurations (conventional, dihedral, and polyhedral). This is
achieved by applying the fundamentals of sailplanes to the single-taper wing
planform in this study. Various attacking angles from 0° to 15° were tested in
the research using a high-lift low-speed airfoil, the AG-16, and a constant low
Reynolds number of 3 × 105. SOLIDWORKS software was used to model the
wings under investigation, while ANSYS Fluent software was used to run the
simulation. All of the examples under study used the same mesh type, number of
elements, and operating condition of airflow velocity as parameters. A correct
mesh resolution was achieved by suitably adjusting the accuracy of the findings.
The results were then contrasted and verified. According to the early findings,
a polyhedral wing design may significantly enhance aerodynamic performance. Due
to the reduction in wingtip vortices (vortex drag), which decreased the induced
drag and improved aerodynamic efficiency, the results were particularly
noticeable at high angles of attack.
